Geometric morphometric comparison between modern homo sapien skulls of south india and rest of the world

Abstract

Morphometry can be defined as the measurement of shape irrespective of the variations of size (scale, translation and rotation). In the recent years, a lot of work has been done world-wide to analyze the variations in the human morphology.Most of the work in this direction was done mainly on African or American population. Lack of work on Indian population arouse our interest to make a study on the same. In the present work, we planned to compare the modern Homo sepien skull of South India and modern Homo sepien skull of world-wide important African male, Australian aboriginal male, African-American male etc. and tried to establish a relationship between them according to their shape. It has been successfully established the relation between the skulls according to the shape closeness. Specimen 10 (South Indian Skull)and 11 (South Indian Skull) have similarity in skull shape which shows the correctness of our result. Specimen 0 (Mongoloid Skull) and 6 (Human Male African-American Skull) show similar shape variation. Specimen 12 (Vedaface) is quite close to (Human Male Asian Skull)8 and 7 (Human Female American Indian Skull). But Specimen 9 (Mongoloid Skull) is found to be quite different from all others. A negative result is also obtained by relative warp which contradicts PCA and shows that specimen 10 (South Indian Skull) posseses similar deformation with respect to specimen 9 (Mongoloid Skull) however 11 (South Indian Skull) is also near. Also 0 (Mongoloid Skull) and 6 (Human Male African-American Skull) are far apart. The result obtained is quite enthusiastic and but further studies in this directions on Indian population is highly required.
